The Patty film was debunked pretty strongly earlier this year in a documentary.
No it wasn’t. Asking 90 year old man with memory issues what he did 60 years ago isn’t proof. The film referenced has been know for decades. It was made after not before the event to try and recreate the episode. Bob Gimlin got it backwards. It wasn’t a secret.
You can’t change anitomical features. The hips, knees and elbow joints are in the wrong place for a human. Costume designer Dave Muns who made costumes for movies has said flatly that human would not not be able to fit their head in the “Mask” due to the forehead slope. Here is a link to an abbreviated version. He was a respected creator of costumes for Hollywood movies.

Also, using comparative analysis o the film it’s been fairly well established that subject in the film is between 6 foot 10 and 7 foot 2.
Is this the video where they guy confessed to being BF and his friend filmed it?
Science debunks it as an ape. All apes, including gorillas, have long arms and short legs.
Humans, however, tend to have shorter arms and legs that are about half the bodies length.
If the Pattison film was real, it would mean that Bigfoot is a human species.
